Hi Guys, long time lurker first time writer. I’m just getting into woodwork with a view to making a few cabinets for aquariums amongst other things. Recently I bought myself a brand new 10” contractor saw for about $1000AUD that seemed to fit the bill for the projects I have in mind. Anyway so I’ve got this thing home, put it all together and done some basic pre-start alignment. I’ve then proceeded to cut up some plywood to make a box with and to continue fine tuning the saw in the process. I’ve got an 80 tooth CMT finishing blade on it, a Fenner drives segmented belt, everything is square and straight but I’m getting fairly rough cuts out of it – like you can see blade marks along the wood. I’m thinking the blade might be bent. The dial indicator measured about .012” wobble near the outer circumference. I’ve then proceeded to measure the face of the arbor which had .002” of wobble and then the blade locating shoulder which had about .001” of runout. It was at this stage I came to the conclusion the arbor was bent. The next day I dropped into the store and talked to the manager about it, who seemed to think there was a problem. I dropped the saw in for the “technician” to look at. The next day I dropped by the store to find my saw that had not been disassembled with the photocopied pages of a book that basically said “If your arbor face has more than .003” wobble, you should have it machined or replaced”. The manager now told me there was definitely no problem and the saw was “within specification”. He was however unwilling to furnish me with the specs that he was referring to. Methinks they don’t exist. So I collected the saw bench and put it back into service, and still not real happy with it. Research from speaking to tradespeople, the internet and a book that I bought from the same shop all say that anything above .001” of wobble in the arbor face of a 10” saw is unacceptable – some going to the extent of calling it dangerous. The other thing is that regardless of the allowable wobble being .001” or .003” these measurements are based on wear and tear on a saw and do not refer to a brand new, out of the box unit. I’m considering taking this issue further and I really would like to get some input from the members of this great site. So what do you think – is the saw faulty or is it ok? -- Blinded by brilliance
